Organic Chemistry Seminar: Nano-Patterned Polyelectrolyte Multilayers: A Non-Lithographic Approach

Abstract:

Nano-patterned materials exhibit unique properties, such as increased surface area and morphology-dependent response. However, obtaining nanoscale patterns usually requires the involvement of electron beam lithography, which is limiting when device-scale patterns (typically spanning square centimeter areas) are sought.

The presentation will describe a modular approach for the construction of nano-patterned polyelectrolyte multilayers. This approach utilizes the nano-patterns that are formed spontaneously in thin films of block copolymers as templates, which guide the assembly of polyelectrolytes using electrostatic layer-by-layer deposition.
